The Goldberg is located at an altitude of 649.1 meters above normal zero. The Goldberg, 1.5 km northeast of Ormont, is a volcano that was created about 10 to 11,000 years ago in two eruptions. First, a large ash cone was formed. After a short break, the second eruption phase began, which at first exploded the top of the old cinder cone with a strong explosion. Then again a cinder cone was built up on the leftovers, and after a certain time the activity ceased. The volcano was built on a plateau of the tertiary Peneplaine at about 610 m altitude. It was originally much taller than 649 meters which it had before mining. Likewise, its extent was much greater, especially to the west. The valleys were not nearly as cut as they are today. Unlike most volcanoes, the Goldberg consists not of lava but tuff. This feature is characteristic of volcanoes on the periphery of an area. The Goldberg is the westernmost point of the quaternary volcanic area in the Eifel, which extends over a width of 12 km and a length of more than 50 km from Bad Bertrich to Ormont. In the tuff we find lapilli, augite crystals, olivine, feldspar, hyalite drops and biotite. From the biotite, popularly called Katzengold, the mountain and probably also the place has its name. In 1958, a deeper arched tunnel with finished and semi-finished millstones was discovered on the northern slope of the Goldberg. The millstones of hard lava basalt were used in the tanning factories of Prüm, Neuerburg, Sankt Vith, Malmedy and Stavelot. Since the end of the 19th century, the Goldberg is mined. The sand (tuff) is an ideal road bed for road construction.
